Inosinic acid or otherwise known as IMP is a nucleoside that is important in metabolism. It is found naturally in many animals but commercially is prepared by yeast or bacterial fermentation using Brevibacterium, Arthrobacter, Microbacterium and Corynebacterium of molasses, starch, sugar beets, and sugar cane. It can also be prepared from meat or fish (sardines). It is essentially an odourless, white crystal or crystalline powder that is very soluble in water. Commercially it is used as a flavour enhancer in foods as it has the ability to make bland and tasteless food taste wonderful.http://www.creative-enzymes.com/product/Inosinic-Acid_470.html
